SITREP 13.03.2025: Ukraine withdraws from Kursk.

Over the past 10 days, a Russian offensive pushed Ukrainian forces out of the Kursk salient, ending a 7-month operation.

What happened? Why did Ukraine withdraw? What’s next? 🧵

You can read a longer version on our Substack

1/ Image
In August a Ukrainian offensive captured over 1200 km² of Russia's Kursk oblast.

The claimed goals were to draw Russian forces from Pokrovsk, capture leverage for negotiations and spoil a Russian operation from Sumy. It was likely also meant to shift the discourse.

2/ Image
However, the Ukrainians failed to expand & secure their flanks and over the next 6 months the Ukrainian perimeter in Kursk diminished steadily. By the beginning of March the Ukrainians only held a bit over 300 km² of terrain in a narrow salient around the town of Sudzha.

3/ Image
Ukraine’s position was linked to Sumy via 2 roads, MSR (Main Supply Route) via the border post and and SSR (Secondary Supply Route) near Oleshnya

By Feb, The Russian capture of Sverdlikovo created a bottleneck, turning these routes into kill zones for Russian FPV drones.

4/ Image
With drones watching both roads and mild winter conditions making off-road movement difficult, Ukraine’s supply lines were crumbling.
Meanwhile, Russian forces managed to form a small bridgehead over the Psel River near Kurilovka.

On March 5, they attacked westward.

5/ Image
Ukrainian sources claims that the two Russian battalions in this attack were North Korean troops. While plausible, there’s no hard evidence yet.

Nevertheless, by March 6, Russians severed the SSR, leaving the MSR as the only route in and out.

The situation turned critical.

6/ Image
The advance threatened to cut off the entire Ukrainian force in Kursk, especially if another pincer was launched from the north.

Ukraine counterattacked, containing the Russian forces but failing to push them back.

At this point, the entire operation was collapsing.

7/ Image
As the SSR was lost, Russia launched a renewed attack in the north, hitting Malaya Loknaya and Martynovka.

Ukrainian forces began withdrawing to Sudzha and Kazachya Loknaya, likely not as a planned retreat but in response to battlefield realities.

8/
In the rear, Russia bombed key bridges over the Loknaya, Sudzha, and Psel rivers, forcing Ukrainian soldiers to flee on foot—some marching over 30 km.

Drone footage showed Ukrainian infantry withdrawing in tight columns prioritizing speed over cover.

9/ Image
Russian milbloggers posted videos of dead Ukrainians and captured equipment, including an intact M1 Abrams.

Soldiers who made it back to Sumy indicate the retreat was in part chaotic and poorly coordinated—possibly initiated at the local level before higher-ups reacted.

11/
Okay, a few words on the pipeline bandits:

A Russian force infiltrated Ukraine’s rear via an abandoned gas pipeline.

Emerging near Sudzha, they moved into forested areas.

Ukraine hit them with cluster munitions, but their ultimate fate remains unclear.

12/ Image
Ukraine claims the infiltrators were destroyed. Russia says they pushed north & south instead, capturing Kubatkin and threatening retreat routes.

Initial reports put the force at ~100 men, later claims suggest 400–800. A battalion-sized unit seems plausible.

13/ Image
Whether they fully achieved their objectives is unclear, but their presence likely contributed to local Ukrainian commanders’ decision to withdraw.

This infiltration was likely a factor in destabilizing the already crumbling Ukrainian defense.

14/ Image
Despite all this, Ukraine regrouped at Kazachya Loknaya and Sudzha, delaying Russia and buying time.

By March 11, Russia took Kazachya Loknaya. On March 12, they raised flags in Sudzha.

By March 13, only a few km² of the Kursk salient remained in Ukrainian hands.

15/ Image
Officially, Ukraine denied abandoning Kursk even when Russian troops were already in Sudzha. In reality, the salient was clearly lost, with little value left.

Fighting will likely continue in Sudzha’s outskirts and border villages as the operation wraps up.

16/ Image
So what happens now?

The key question: How many troops & how much equipment did Ukraine save?

While Russia didn’t fully encircle the northern salient, some Ukrainian units were lost. Prisoner footage remains limited but may increase in coming days.

17/ Image
Some Ukrainian soldiers compared the withdrawal to Debaltseve (2015).

It’s likely Ukraine abandoned most heavy equipment that was still in the salient due to drone threats over their final supply route.

The number of casualties and lost equipment is still unknown

18/ Image
Ukraine will likely fall back to defensive positions in Sumy. After that, the next steps are uncertain for both Russia and Ukraine.

Russia holds the initiative but they could either -Press into Sumy, forcing Ukraine to commit more troops -Shift forces to Donetsk
19/ Image
If Russia focuses on Donetsk, Ukraine could also shift its withdrawn Kursk forces eastward, while pushing onto Sumy would force Ukraine keep a force there.

We believe Russia will more likely maintain some pressure on Sumy, limiting Ukraine’s ability to reposition.

20/ Image
Some have claimed that Russia’s advance was due to the pause in US intelligence sharing. We disagree. The operation’s scale suggests planning and preparations started well before the pause in intel sharing forewarning. No major disruptions were seen on other fronts.

21/ Image
That said, the intelligence pause may have caused local disruptions, but it wasn’t the decisive factor. The real issue was Russian pressure on Ukrainian logistics—once supply lines were cut, withdrawal was inevitable

We have seen this play out multiple times during the war.

22/ Image
Russia has used large-scale infantry assaults successfully before. The collapse followed familiar patterns. At most, the intel gap worsened situational awareness, but did not cause the collapse.

The situation was likely exasperated by the pulling back of drone units.

23/ Image
The Kursk operation started as a bold Ukrainian gamble but ended in retreat.

Did it achieve its goals? Was it worth the cost?

Unsurprisingly my personal answers to both are "no" and "no".

I'll elaborate on that next time.

Meanwhile we have a much longer version of this post up on our blog. You should go and check it out. I'll link to it below this tweet.

We also thank all the colleagues whom we've followed these developments with, and of course, @wihurinrahasto which keeps us running.

This naturally should not just randomly have to word "forewarning there". Twitter decided to play with me and I had to repost a bunch of stuff and do some edits, leading to this.
One additional map of the northern retreat, which, for some reason, was not added to the post about captured equipment. Image
For some reason this picture was not added to this post: Image

I think there is some flawed logic here. In general the article fail to compare and contrast the Ukrainians and the Russians on similar grounds.

To an outside observer it feels like picking and choosing talking points instead of a completely honest assessment of the situation. Image
For example, the authors engage with assessments of Russian casualty numbers, yet fail to mention how Ukrainian officials have multiple times now published UA casualty numbers that indicate, at best, a 1:2 overall casualty ratio.

Current ratios may, naturally, differ from that.
It also ignores the enduring Ukrainian manpower issue that Ukraine has seemingly been unable to solve, while Russian recruitment is, according to Ukrainian intelligence, able to replace the casualties it's taking in Ukraine.

One needs to consider that when talking of attrition.

With the recent Russian advances, two dangerous salients are emerging in Southern Donetsk.

In Velyka Novosilka and Kurakhove, the Ukrainian supply routes are under significant threat.

A quick thread on the situation in South Donetsk. 1/

1/ Image
General situation:

Although the Russian pace of advance slowed in December they've continued their advance in southern Donetsk.

Pictured in darker red is the situation at the beginning of December, light red is Russian advances.

2/
The most difficult situation has emerged around the Kurakhove salient where the Russians are advancing both on the northern and southern flanks.

The Ukrainian situation here is especially dangerous because of the limited logistical routes.

SITREP: South Donetsk

After breaching Selydove and Hirnyk early in the week, the Russians started offensive operations in the Vuhledar direction on Friday..

Due to these developments the situation on the South Donetsk frontline has turned very difficult.

Dark red = 20. OCT

1/ Image
Vuhledar front:

On Friday the Russians began large scale attacks towards Shakhtarske and Bohoiavienka.

They gained ground quickly, advancing almost 7km towards Shakhtarske.

These attacks were supported by large scale artillery and air bombardments.

2/
In Bohoiavienka the Russians had managed to advance within 3km of the town before Friday.

Although the initial attacks may have been repelled, video footage from Bohovienka and reports from Shakhtarske indicate that Russians have a strong foothold in both villages.

After a few weeks of (relatively) lower intensity actions, the Russians have resumed offensive operations in the Selydove-Hirnyk area, south of Pokrovsk.

In the past few days, we've seen the Russians make tactical gains throughout the AO.

Selydove direction, a thread.

1/ Image
As said, after an operational pause and transfer of reinforcements, the Russians have restarted offensive operations.

They are taking advantage of Ukrainian lack of manpower and using infiltration tactics, sending small infantry units through gaps in the Ukrainian line.

2/
The Russian advance here has been relatively rapid, over the past three days. Pictured is the confirmed change since monday.

According to unconfirmed reports, the Russians may control much of the grey area.

Confirmed advance is up to 2,6 kilometers, but likely further.

Just a reminder, at least a part of the 59th is in the salient north of Krasnohorivka.

We've repeatedly seen the willingness of the Ukrainians to spend lives over territory, but in recent months these sort of complaints from the front have become increasingly common
Image
With the experienced brigades being drawn to Kursk and getting replaced with greener ones, and with increased pressure, it seems the UA high command is expecting to do more with less. If the line doesn't hold it seems the blame is pinned on the soldiers, not the orders.
Some have blamed the increase in these sort of orders and repercussions on Syrskyi, and I there may be some truth to it.

However, we also saw these style of stubborn static defense actions in Bakhmut and under Zalushnyi.

So I think it's a political/strategic demand.

Some thoughts on today's tragedy in Poltava.

Many Ukrainians are justifiably angry due to the strike at the 179th training centre with more than 250 casualties

As has been the case lately, the anger is directed not just at the Russians but at their own leadership as well. Image
Many Ukrainians have pointed out that this isn't first time something like this happens. There have been multiple mass causalty events caused by the Ukrainians housing large numbers of soldiers in pre-war military facilities.

Yavoriv, Mykolaivka, Desna... Image
Some have also pointed to the strike on the 128th brigade from last november.

Time and time again negligent leadership leads to preventable Ukrainian casualties. Time and time again no-one is held responsible.

This also applies to many situations on the frontline itself.
